Intracellular Digestion Intracellular digestion occurs within a cell. The cell will take in nutrients that still need to be broken down so they can be used. Extracellular Digestion Extracellular digestion occurs outside the cells. Cells will dump enzymes into a environment to digest food. The pancreas will dump digestive enzymes into the small intestine to finish digesting carbohydrates, fats, and protiens. Why did Kim tell James the he would be sick after eating the raw pork?
